ABB 1SFA896103R7000 PSR3-600-70 Soft starter is a compact motor starting device designed to reduce the mechanical and electrical stress associated with direct-on-line starting of three-phase induction motors. It controls the motor voltage during starting and stopping, providing a smoother acceleration and deceleration profile for applications such as pumps, fans, compressors and conveyors. The PSR3-600-70 operates over a broad 208–600 V AC main voltage range and uses a 100–240 V AC, 50/60 Hz control supply. ABB’s India catalog rates this model at 3.9 A and 1.5 kW / 2 HP. The PSR family uses two-phase control and incorporates a built-in bypass, which helps reduce internal losses once the motor has reached normal operating speed. The soft starter provides easy front-panel adjustment of starting and stopping parameters using potentiometers. A RUN relay output is available for status signaling, while optional fieldbus connectivity can be added through an external adapter and Fieldbus Plug. ABB notes that PSR soft starters are commonly combined with an ABB manual motor starter for upstream motor and short-circuit protection.
